<p>
You and x other people have been given $y. Each of must decide whether to keep your money or contribute it to a community pot.
Once you have all made your decisions, the community pot will be doubled and distributed evenly to every member of the group.
</p>

<p>
As an example, if you and 4 other people choose to contribute, there will be $5y in the community pot.
This money will then be doubled, so that there is $10y in the community pot. Then each member of the group will get an equal share of the community
money, in this case $10y/x.
</p>

<p>
At the end of this game, those who contributed would earn their share of the community money ($10y/x), while those who did not contribute
will have the amount they began with ($y) plus their share of the community money ($10y/x), totaling $y+10y/x.
</p>

<p>
If no one contributes, each of you will earn only the $y you received at the beginning of the task. If everyone contributes, you will each
receive $2y (your share of the community pot after it has been doubled).
